That temp seems to be higher than normal. My temp also sits just above the 180 mark. With yours in the 215 range I would be doing a system check out. Check to see if the coolant temp is true, the fans (both) are coming on when they're suppose to, the water pump is flowing coolant (impellor blade integrity?, if the blades are coming apart...are there pieces plugging water galleries?), thermostat operating properly?
Good luck and let us know what you find.
